## Summary

A TikTok claiming that Anthropic engineers build self-improving agentic systems by combining tight feedback loops, "dreaming," and a CLAUDE.md config file. The core message: close the agent loop and give the agent a way to verify its own output. Caption-only, so the deeper mechanics aren't captured here.

## Key Insight

- **Close the loop = let the agent check itself.** The single repeated tactic is giving an agent a way to verify its own output rather than firing one-shot prompts and trusting the result.
- **Self-verification is the unlock for "self-improving" behaviour.** An agent that can grade/test its own work can iterate toward a correct answer without a human in the middle.
- **CLAUDE.md as persistent guidance.** A project-level config/instructions file is cited as part of the setup, durable context the agent reads on every run.
- **"Dreaming"** is named but not defined in the caption (likely speculative/exploratory iteration). Treat the "90% of engineers" stat as an unverified claim from a creator, not an Anthropic source.
